Vēža ģenētiskās testēšanas laboratorijas izveide Rīgā
2016
Onkoloģiskā saslimšana ir mūsdienās viena no smagākajām diagnozēm, no kuras ik gadu mirst liels cilvēku skaits pasaulē un Latvijā. Katru gadu pieaug pacientu skaits, kuriem ir diagnosticēts kāds no ļaundabīgā audzēja veidiem. Onkoloģijas pacienti ir visas pasaules mēroga problēma, un arī Latvijā vēža pacientu skaita pieaugums ir epidēmijas līmenī pašlaik. Diemžēl Latvijā ir novērojama tendence, ka vēzis tiek diagnosticēts vēlajās tā stadijās. Vēža diagnosticēšana tā agrākajā stadijā nozīmē pacienta dzīvildzes rādītāju pagarinājumu vai pat slimības remisiju. Vēža ģenētika sniedz visaptverošu informāciju par vēža slimības attīstību, tās iespējamajām lokācijām un daudzos gadījumos ar ģenētiskā…
Evidence of a causal effect of genetic tendency to gain muscle mass on uterine leiomyomata
2023
Uterine leiomyomata (UL) are the most common tumours of the female genital tract and the primary cause of surgical removal of the uterus. Genetic factors contribute to UL susceptibility. To add understanding to the heritable genetic risk factors, we conduct a genome-wide association study (GWAS) of UL in up to 426,558 European women from FinnGen and a previous UL meta-GWAS. In addition to the 50 known UL loci, we identify 22 loci that have not been associated with UL in prior studies. UL-associated loci harbour genes enriched for development, growth, and cellular senescence. Of particular interest are the smooth muscle cell differentiation and proliferation-regulating genes functioning on t…
Functional characterization of osteosarcoma cell lines provides representative models to study the human disease
2011
Cancer cell lines represent in vitro models for studying malignancies, general cell biology, drug discovery and more. Whether they can be considered as exact representative models of the parental tumors remains uncertain given the acquisition of additional ex vivo changes of the cells and the lack of tissue architecture and stroma. Previously, within the EuroBoNeT consortium, we characterized a collection of bone sarcoma cell lines on genomic and proteomic level. Here, we address the phenotypical and functional characterization of the unique set of osteosarcoma cell lines (n=19) in vitro and in vivo. For functional analysis of differentiation capacity, cells were stimulated towards osteobla…
